Established Maximum Residue Limit: Piperonyl butoxide  
The proposed maximum residue limit (PMRL) document for piperonyl butoxide notified in 
G/SPS/N/CAN/1490 (dated 13 March 2023) was adopted 12 July 2023.  
As per PMRL2023 -16, the revocation of the MRL for piperonyl butoxide on raw cereals will take effect

adoption of the revocation in the MRL database will be on 2 March 2026, 36 months from the date of 
publication of RVD2023 -07 (published 2 March 2023).  
MRLs established in Canada may be found using Health Canada's Maximum Residue Limit Database  
(https://pest -control.canada.ca/pesticide -registry/en/mrl -search.html ) on the Maximum residue 
limits, human health, and food safety webpage ( https://www.canada.ca/en/health -
canada/services/consumer -product -safety/pesticides -pest-management/public/protecting -your-
health -environment/pesticides -food/maximum -residue -limits -pesticides.html ). The database allows
